On pulling git gives warning: unable to rmdir 'fonts': Directory not empty, but that is easy to miss out. The leftover directory is tentatively cleanable via git clean which knows how to take in account git ignore list or whether a subdirectory is tracked by git.

Then in dry run (--dry-run) node on production:

$ git clean --dry-run -d --force --force
Would remove wmf-config/scap

Which is a leftover empty directory not showing in git status (since it is empty). I will remove it.

Then git clean is easy to shoot oneself in the foot and given we only update submodules in operations/mediawiki-config every 3 years or so, I am tempted to skip implementing a cleanup step.
